Fertility rite
Fertility rites are religious rituals that reenact, either actually or symbolically, sexual acts and/or reproductive processes: 'sexual intoxication is a typical component of the...rites of the various functional gods who control reproduction, whether of man, beast, cattle, or grains of seed'.
They may alternatively involve the sacrifice of 'a primal animal, which must be sacrificed in the cause of fertility or even creation', while there is evidence that 'prehistoric mother worship in the form of fertility rites is tied to human sacrifice'.
Characteristics
"Fertility rites may occur in calendric cycles, as rites of passage within the life cycle, or as ad hoc rituals....Commonly fertility rituals are embedded within larger-order religions or other social institutions."
As with cave pictures"[which] show animals at the point of mating...[and] served magic fertility rites", such rites are "...a form of sympathetic magic" in which the forces of nature are to be influenced by the example acted out in the ritual. At times, "ceremonies intended to assure the fecundity of the earth or of a group of women...involve some form of phallic worship".
